There’s a reason for all of the rainfall.
“It’s kind of a unique pattern,” National Weather Service meteorologist Jason Dunn said. “There’s a very high pressure system over the west, and a high pressure system over the southeast, and those have set up a blocking pattern keeping the weak low pressure between the two.”
A “very persistent low pressure system” has been hovering above Texas and the southern plains for the past few weeks, Dunn said, sucking in “plenty of moisture” from the Gulf of Mexico and causing record amounts of rainfall and flooding throughout the state.
While the system will eventually break down, the area will continue to see more scattered showers and thunderstorms. Although some small windows for drying out will show up throughout the week, there will be “no real significant period without rain” during the next week to 10 days, Dunn said.
The NWS forecast for Sunday, July 8, through Thursday, July 12, calls for a 20 percent chance of scattered showers and thunderstorms and partly cloudy skies each day.
The National Oceanic and Atmospheric Administration urges residents to avoid driving through high water, noting, “You will not know the depth of the water nor will you know the condition of the road under the water.”
Vehicles - even trucks and large SUVs - can be swept off the road by water as shallow as 18 to 26 inches, and people can be swept off their feet by as few as 6 inches of swift water.
Due to the continued rain, several roads throughout the county are and potentially could be closed due to high water or bridge damage.
Two roads in Pct. 1 were closed as of Friday afternoon, with Neck Road being closed due to bridge approach damage and Parker Hill Road closed due to high water.
If heavy rains fall, Palmyra, Sutton, Ebenezer, Gibson and Bluff Springs roads could all pose high-water risks, Commissioner Dennis Robinson said.
In Pct. 2, Walker Creek Road, Oil Field Road and Spence Road were all underwater Friday afternoon, with the possibility Union Hill, Sandswitch “and almost any of the ones east of I-45” could go underwater if more rains come, Commissioner Bill Dodson said, saying, “There have been roads I’ve never seen water over that have had 6 or 8 inches of water over them.”
In Pct. 3, Cosby Road, Bell Branch Road, Ozro Road, Lo Water Road and the intersection of White Rock and Shield are all closed and will remain closed through the weekend.
In Pct. 4, road and bridge foreman Erick Thompson said Ray White Road was closed due to high water, and Westmoreland, Patrick, Sterrett and Bob White roads are all at-risk.
If heavy enough rains fall, the bridges on Shawnee and Hampton could also be considered at-risk, Thompson said.
